30 students were asked which the preferred pizza or cake. 80% said pizza. How many is that?

24 students

Step-by-step explanation:

All you have to do is make 80% into a decimal (.8) then multiply it by 30 and you get 24!

I hope this helps, and have a great day!

P.S. I agree with the 80%

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.

w'x is 0.

hope it
